Function - Returns system information.
INFO : DINT Identifier of the requested information
Q : DINT Value of the requested information or 0 if error
The INFO parameter can be one of the following predefined values:
| _SYSINFO_TRIGGER_MICROS | programmed cycle time in micro-seconds |
| _SYSINFO_TRIGGER_MS | programmed cycle time in milliseconds |
| _SYSINFO_CYCLETIME_MICROS | duration of the previous cycle in micro-seconds |
| _SYSINFO_CYCLETIME_MS | duration of the previous cycle in milliseconds |
| _SYSINFO_CYCLEMAX_MICROS | maximum detected cycle time in micro-seconds |
| _SYSINFO_CYCLEMAX_MS | maximum detected cycle time in milliseconds |
| _SYSINFO_CYCLESTAMP_MS | time stamp of the current cycle in milliseconds (OEM dependent) |
| _SYSINFO_CYCLEOVERFLOWS | number of detected cycle time overflows |
| _SYSINFO_CYCLECOUNT | counter of cycles |
| _SYSINFO_APPVERSION | version number of the application |
| _SYSINFO_APPSTAMP | compiling date stamp of the application |
| _SYSINFO_CODECRC | CRC of the application code |
| _SYSINFO_DATACRC | CRC of the application symbols |
In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung. In IL, the input must be loaded in the current result before calling the function.
Q := GETSYSINFO (INFO);
(* The function is executed only if EN is
TRUE *)
(* ENO keeps the same value as EN *)
